Cool factor for me this episode was:

[Soma]: Subject E-57!
Hallelujah clocks gun in face
[Hallelujah]: That's me, bitch.

Too bad the shot didn't go off.

As Ryll said, GN Armour wtf. Guess having complete access to Veda and the UN gives you ample info and resources to build something like that though. Most emotional impact was stolen by Lockon last ep, but this was still quite heavy. Christina's in particular. The blast only hit the bridge, right? With Haro in Dynames, if he ever comes back, I'll be expecting "Lockon! Lockon! Lockon!" over the com.
